Schematic of the NanoLockSpray source:
Sample inlet
Spray indexing permits acquisition of sample and LockSpray data in separate
data channels, and the baffle design ensures negligible cross-talk between the
two sprays. The LockSpray data are used to calculate a correction factor for
the mass-scale calibration, which is then applied to the sample data, providing
exact-mass information.

Sample sprayer

You can use the NanoLockSpray source with different NanoFlow sprayers.
